This mask is horrible. The headgear takes forever to get on and get adjusted properly. It usually will leak and the mask parts are not built very sturdy, it has a lack of adjustment for the forehead. The forehead cushion is hard and caused me to get headaches due to the pressure applied by the two gel cusions. The mask seal is interchangeable with the old version of the serenity mask, which I loved but, has been discontinued now. I am very disappointed with this radically changed mask, and I will not buy from this manufacturer again.
